Squeaking after a turn

1992 Isuzu bighorn - makes squeaking sound during and after turning. Sound goes away after going straight for some time. Initially thought problem with belts as previously sound appears when starting. After belt replacement, sound appears only during and after turning. Does this indicate power steering problem? How can it be fixed. Thanks folks.

Im having the same problem..squeaking comes from the front whenever i turn the steering but only when the air-conditioning unit is turn on, when it is not everything seems normal..but sometimes when the aircond unit is turn on there are no squeaking but when i turn the wheel it comes again then the squeaking continues untill i turn off the aircon unit...

When I put my foot on the brake the right turn signal comes on. When I use my right my right signal it wont blink
with my foot on the brake pedal. When I use my left turn signal my hazard lights work...
